Bulb-type lighting source |
摘要 |
A bulb-type lighting source employs a light-emitting element in a structure that facilitates heat dispersal. The lighting source includes a first heat sink member mounted in a bowl shaped case supporting a power supply circuit. A mounting substrate is positioned in surface contact with a surface of the heat sink member and is capable of supporting a light-emitting unit. A globe covers the light-emitting unit to permit light emission. A second heat sink member has a surface in contact with a perimeter of the mounting substrate and offset from the light-emitting unit to provide a second part in surface contact with the first heat member to facilitate the release of heat.
